Shaanxi Qianyi Tuoda Technology Co., Ltd provides complete tubular‑solution for global EPC contractors, chemical plant operators, heat‑exchanger fabricators, offshore oil‑gas project teams and international trading houses. Our product portfolio covers hot‑extruded & cold‑drawn seamless nickel‑alloy pipe, condenser tube and heat‑exchanger tube, which are heavily deployed in harsh‑medium process piping, salt‑lake lithium extraction circuits, seawater desalination units, offshore subsea pipelines, flue‑gas desulfurization scrubber systems, petrochemical high‑temperature loops, hydrofluoric‑acid processing equipment and corrosive‑medium power‑plant heat‑exchange circuits. We handle small‑batch sampling orders, medium‑size project call‑offs and large‑volume bulk export shipments. Apart from standard stocked OD‑WT‑length combinations shown in specification table, we produce non‑standard tubular goods per customer’s engineering drawing, including special wall tolerances, fixed random lengths, end‑bevel preparation and extra non‑destructive‑testing packages.
Each nickel‑alloy grade follows its dedicated ASTM specification: pure Nickel 200 / Nickel 201 seamless pipe complies with ASTM B161; general‑purpose heat‑exchanger & condenser tube follows ASTM B163; Hastelloy C276 seamless pipe adopts ASTM B622; Monel 400 implements ASTM B165; Inconel 625 follows ASTM B444; Incoloy 800 series complies with ASTM B407; Incoloy 825 is governed by ASTM B423; ASTM B829 defines general common requirements for all nickel‑alloy seamless tubular products. Every batch can deliver EN 10204 3.1 mill‑test‑certificate covering chemical composition, mechanical test records, heat traceability, PMI verification and non‑destructive‑test reports for third‑party witnessing, project‑archive filing and overseas customs clearance. Different alloy densities directly affect theoretical‑weight calculation: Nickel 200/201 = 8.89 g/cm³; Monel 400 = 8.80 g/cm³; Hastelloy C276 = 8.89 g/cm³; Inconel 625 = 8.44 g/cm³; Incoloy 800 = 8.11 g/cm³; Incoloy 825 = 8.25 g/cm³.
Our warehouse maintains 50‑60 tons ready‑stock covering mainstream outer‑diameter, wall‑thickness combinations of nickel‑alloy pipe and tube. Monthly overall supply capacity can reach up to 100 tons to satisfy tight‑delivery‑schedule project demands. Nickel‑alloy raw‑material price closely links to LME nickel spot‑market fluctuation, static fixed quotation is not available. All worldwide purchasers shall refer to our official weekly price‑list for real‑time updated offer. When submitting RFQ for custom nickel‑alloy pipe, send us the drawing, material grade, dimensions, tolerances, service conditions, inspection requirements, and destination. Our engineering‑sales team will evaluate theoretical weight, unit price, production lead‑time and complete inspection scope for your project.
Important Note: Weight figures in this table are purely theoretical reference values only. Actual delivery weight shall be subject to physical weighing and official MTC report. Calculation formula for round seamless pipe:
Hot‑extruded seamless pipe has dimensional tolerance defined by corresponding ASTM standards; cold‑drawn precision tube owns tighter wall‑thickness tolerance. Wall‑thickness deviation, surface pickling removal allowance will generate actual‑to‑theoretical weight deviation ranging ±3%‑7%. Theoretical weight applies for budget estimation, container‑loading calculation and preliminary quotation, cannot replace physical weighing for commercial settlement. Negotiate weight‑acceptance criteria with our sales engineer before formal contract signing.

Nickel 200 / Nickel 201: commercially pure nickel. Nickel 200 suits general alkaline‑medium piping; Nickel 201 ultra‑low‑carbon grade prevents intergranular corrosion under high‑temperature caustic condition, for caustic‑soda process pipelines and alkaline heat‑exchanger tubing. Monel 400 nickel‑copper alloy delivers outstanding seawater and hydrofluoric‑acid resistance, widely adopted for marine piping, brine‑processing circuit and desalination process tube. Hastelloy C276 nickel‑chromium‑molybdenum‑tungsten alloy resists mixed oxidizing‑reducing corrosive fluids including wet chlorine, ferric‑chloride, complex mixed‑acid media, the primary selection for FGD scrubber piping and severe‑corrosion chemical‑plant pipelines. Inconel 625 is niobium‑molybdenum strengthened alloy balancing high‑temperature strength and chloride pitting‑corrosion resistance for offshore high‑pressure process piping. Incoloy 800 nickel‑iron‑chromium alloy provides excellent high‑temperature carburizing‑resistant performance for furnace‑loop and high‑temperature heat‑exchanger circuits. Incoloy 825 adds molybdenum‑copper element to resist sulfuric‑phosphoric mixed‑acid and chloride‑ion attack, heavily used for salt‑lake lithium‑extraction and sour‑service oil‑gas tubing systems.
It is critical for purchasers to distinguish seamless nickel‑alloy pipe versus welded nickel‑alloy pipe, these two products are not interchangeable in most critical‑service projects. Seamless pipe is hot‑extruded or cold‑drawn from solid billet without longitudinal weld seam; cross‑section microstructure remains homogeneous, no weld‑heat‑affected‑zone corrosion risk. It is the preferred option for high‑pressure, cyclic‑load, sour‑service, high‑temperature and high‑corrosion‑risk piping, though cost is relatively higher. Welded pipe is roll‑formed from plate‑coil and TIG‑welded, cost‑effective for large‑diameter, medium‑low‑pressure non‑critical‑service projects, yet weld seam requires full‑range radiographic inspection to eliminate weld‑defect hidden‑trouble. Our main stock focuses on seamless nickel‑alloy pipe & heat‑exchanger tube; welded nickel‑alloy pipe can be produced upon special customer drawing requirements.
For nickel‑alloy pipe RFQ, besides grade, OD, WT and length, you must clarify full inspection package according to project specification: PMI positive‑material‑identification to verify alloy chemistry, hydrostatic test (mandatory per most ASTM tubular standards), eddy‑current‑test (ET) for small‑diameter heat‑exchanger tube, ultrasonic‑test (UT) for wall‑internal‑defect detection, end‑bevel requirement, surface finish (pickled / bright annealed), heat‑treatment condition, MTC document standard and third‑party witness requirement. Our mill can perform above‑mentioned full‑scope inspections. All export‑oriented nickel‑alloy pipe adopts seaworthy fumigated plywood crate packaging, end‑plastic‑cap protection, moisture‑proof wrapping paper to avoid scratch, collision and damp damage during long‑ocean‑voyage logistics.
As one‑stop corrosion‑resistant‑metal supplier, Shaanxi Qianyi Tuoda Technology also provides supporting titanium series products, nickel‑alloy plate, nickel‑alloy bar, nickel‑alloy flange and zirconium‑base material. Consolidate multi‑category material procurement from single manufacturer to reduce multi‑supplier communication overhead, cross‑batch‑inspection coordination risk and complex delivery‑management workload. Please keep reminding that theoretical‑weight data in above‑mentioned table comes from ideal nominal dimension and alloy density, wall‑thickness tolerance, pickling stock‑removal will generate weight deviation, theoretical‑weight cannot be used for commercial settlement.
If you need to compute theoretical weight for non‑stock custom outer‑diameter, wall‑thickness or special‑length dimensions not covered inside our specification table, please open our dedicated online nickel‑alloy‑pipe weight‑calculator webpage for fast calculation:
